, 2009 公共项目绩效评估指标体系是一个具有特定结构与功能的复杂系统,为了避免该指标体系设计陷入主观随意、过于复杂的局面,我们可以以公共项目样本属性、项目利益相关人等重要因素为切入点,来构建“绩效维度-利益相关者-样本属性“三维立体的绩效评估指标体系。通过探讨构建公共项目三维立体绩效评估指标体系的缘由,解析绩效维度、利益相关者及样本属性内涵,指出该指标体系是现代思维、理性思维、哲学思维的综合演绎,且在众多设计开发思路的理论基础中存在共性因子,特别是以当前最具有代表性的基础设施建设项目、社会公益性项目作为研究对象 ...

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Zhejiang Daxue xuebao. Lixue ban, 2022 针对注水开发的多层砂岩油藏分层动态分析难度大等问题，在常规井层开发指标计算基础上，结合动、静态劈分方法，综合考虑渗透率、孔隙度、地层系数、含水饱和度、位置系数、措施系数及注水量系数，提出了一种既可将油、水井作为统一整体，又可对小层、方向流动分量开发指标进行定量计算的体现渗流力学本质的方法。用大庆油田N2-O1井组的产液剖面资料进行验证。结果表明，所提方法的计算结果与测量结果吻合度较高，精度平均值达75.11%。用该方法计算开发指标，适用性强，能较真实地反映各小层、各方向的产液情况，对现场应用具有指导意义。

教育研究, 2019 教学督导评估不仅要对教师的教学能力和教学效果做出评估,也应该对学生学习的态度和学习效果进行评估,然而,目前我国地方高校的教学督导评估工作尚未建立起较为完善的教学评估指标体系,因此没能达到应有的教学督导评估效果。论文对地方本科院校教学督导评估指标体系的建立和运行提出了一些建议。
